Today participants worked in small groups to design a scavenger hunt for their peers. Using cryptography and pattern recognition, students designed and shared their scavenger hunt across campus. The process of checking their clues, accurately modeling them and distributing them to their classmates was an exciting time for all! The hunt is on!
Ask your student:
Which pattern or cryptography pattern worked the best for you today?
What is the purpose of cryptography? Explain a time in your life when you might want to use it.
What’s Up with Water? Thursday: Sink or Float?
What floats and what doesn’t? What if it’s saltwater, or freshwater? Inquiry and imagination lead our “water-ful” scholars today as they set out to answer these questions. Students worked together to come up with rules on floating items in water, then tested their hypotheses using common household items like straws, corks, and bottle caps.
The students quickly began to notice the effect of density, but still had questions. One student asked, “How are boats able to stay afloat if they’re so heavy?” Their observatory skills were put to the test and they stood up to the challenge!
Vital Signs @ McKendree – Thursday: The Blood Part 1
Today, our scientists delved into the study of blood type and the genetics that help determine it. Students first discovered the physical basis behind the ABO blood type group, analyzing different antigens. In the lab, they attempted to determine the blood type of different samples by creating antibody reactions.
The analysts-in-training also learned the basics of Mendelian genetics, discovering how blood type traits are inherited and why some are dominant over others.
Ask your student:
How many total possibilities are there for blood type? (there are 8 including both genes: A+/-, B+/-, AB+/-, and O+/-)
What is one method to predict the blood type of the offspring when you know that of the parents? (use a Punnett square)
Our volunteers at McKendree had a great time tie-dying nametags!
